and there is more>>direct control versus lateral only finding.
Giro V was presented two years ago as a fully developed Giro
very suited to the average R/Cer. Question, was it confucious who
said there never is a finale?
Investigation and development continue so there are new findings and improvements. Giro V featured lateral rotor control
and there was an ongoing desire to investigate D.C control completely. Later in the year a how to for a simplistic infinite control rotor head was reported and this head became "the one".
For evaluation the origional head on Giro V was simply replaced
by the new infinite had retaining both rudder and elevator controls.
Rudder versus lateral rotor had been previously compared, there
was no contest, lateral rotor was quite superior.
Something similiar was hoped for with rotor pitch control versus
elevator. The disappointment was unexpected. finding:
Using elevator responce was the same as with an airplane. A small amount of "up" elevator created a shallow climb angle with
no loss of air speed. More up increased the angle without marked
speed loss. Finally the Giro could be put into a vertical climb for some distance. Very smooth and desirable pitch control
For comparison the same routine was followed using rotor pitch
control. Actually we never got to the vertical segment, the ability
simply did not exsist.
From level flight the rotor angle of attack was increased creating
a climbing flight path, however, unlike the elevator useage, there
was a marked decrease in air speed. When the attack angle was
further increased the air speed loss was drastic. Increasing the
angle of attack further reduced forward speed more putting the
Giro into a hover mode.
Conclusion: for normal style flying elevator does just fine while
rotor pitch control left much to be desired
Should be said that there may well be flight situations, especially at very low speed where rotor pitch control may be an
asset. indications suggest that. So, the next evaluation will look
into that situation.
Hope is that this may be of interest and help, good luck!!
